[issue33774] Document that @lru_cache caches based on exactly how the function arguments are specified

Speaking frankly, I might not have grasped what might happen by reading your line. I think having at least a minimal example is crucial. Perhaps:

"Distinct argument patterns, such as `f(1)` and `f(first_arg=1)`, may not cache for each other even if the underlying function sees them as equivalent calls."
